**Orelhão** (officially *Telefone de Uso Público*) is the protective shell for public payphones invented by Chinese Brazilian architect and designer Chu Ming Silveira. It was launched on 4 April 1972, first appearing in Rio de Janeiro and São Paulo before spreading across Brazil and reaching other Latin American nations like Cuba, Peru, Colombia, and Paraguay, as well as African countries such as Angola and Mozambique, plus China and other parts of the world.
Public payphones first appeared on Brazilian streets in mid-1971, when the country had over 93 million people and mobile phones did not yet exist. Earlier, in the 1920s, semi-public phones with token boxes had been placed in shops under contract with the Companhia Telefônica Brasileira (CTB), which served São Paulo, Rio de Janeiro, and Minas Gerais. By 1971, about 52 million of Brazil’s nearly 100 million inhabitants lived in urban areas. Noise made street payphones hard to use, so CTB tested 13 circular fiberglass and acrylic cabins in São Paulo. The results were poor: the cabins were uncomfortable, vandalized, and blocked narrow sidewalks.
Chu Ming Silveira, then head of the projects section at CTB’s Engineering Department, took on the challenge. She listed requirements: protect the phone and user, keep costs low for manufacturing, maintenance, and installation, ensure durability against weather and wear, adapt to different areas, provide good acoustics and aesthetics, attract the public, be simple to operate, allow uninterrupted use, project a good service image, add a new urban element, and fit the ergonomics of Brazilian urban users.
She began with an egg shape, which she considered the best acoustic form. The dome’s curvature provided 70 to 90 decibels of acoustic protection, reflecting most outside noise and directing the remainder to a point below the average user’s ear. The booth, made of strong, lightweight, fire-resistant fiberglass that was also cheap, launched in 1972. CTB called it “Chu II,” but it soon became known as *orelhão* (big ear), along with nicknames like “tulip” and “astronaut’s helmet.” The press favored “tulip,” referring to clusters of two or three booths attached by an iron pipe carrying wires. These orange and blue tulips held red phones made in Osaka, Japan, popularly called “reds” or *tamurinhas*. Before the orelhão, Chu Ming had created the smaller “Chu I” or *orelhin

Lore & Background
Chu Ming Silveira, a Chinese Brazilian architect and designer, headed the projects section of the Engineering Department of the Brazilian Telephony Company (CTB). She was tasked with solving the problems of earlier public phone cabins, which were spacious, uncomfortable, and prone to vandalism. Her design, launched in 1972, used an egg shape for optimal acoustics, providing 70 to 90 decibels of noise protection. The booth was made of fiberglass, strong, light, resistant to sun, rain, and fire, and cheap to produce.
The first Orelhões were installed in Rio de Janeiro on 20 January and in São Paulo on 25 January, with 170 units placed in São Paulo. The design was initially called "Chu II" by CTB but gained nicknames like "tulip" and "astronaut's helmet." The press adopted "tulip," referring to the set of 2 or 3 booths attached by an iron pipe. The orange and blue booths featured red telephones from Osaka, Japan. Before the Orelhão, Chu Ming developed the smaller "Chu I" or orelhinha for indoor use, tested in mid-1971.
The Orelhão's success led to export to Mozambique in 1973, and later to other Latin American and African countries, as well as China. In 1975, blue Orelhões for long-distance calls were introduced. Despite vandalism, market research in 1977 and 1978 showed high public approval, with 82% of the population using them and 73% finding them "very presentable."
Reader's Guide
The Orelhão represents a landmark in Brazilian industrial design, combining functionality, durability, and aesthetic appeal. Its egg-shaped fiberglass shell solved acoustic and climatic challenges, making it suitable for Brazil's urban and rural environments. The design's success is evidenced by its widespread adoption across Brazil and export to countries in Latin America, Africa, and Asia. The Orelhão became a cultural icon, featured in advertising and recognized for its role in connecting people. Its legacy includes influencing public telephone design globally and demonstrating the value of thoughtful, user-centered design in public infrastructure. The booth's decline began with the rise of mobile phones and the introduction of phone cards in 1992, but its impact on Brazilian urban life and design remains significant.
